well right now im getting about 14 all together. some highway and some city. my rpms on highway when i go to work at 75mph is like 3200rpms, is that high? ive changed the spark plugs about 6 months ago, the fuel filter about 4 months ago. im gonna check my coils tomorrow. i checked the ecu for codes and all is ok. any other ideas. our gas here in the us is killing me, its making me refil about every 4 days. i have new tires. i just cant think of what else to do. thanks
